Are philodendrons toxic to dogs?

Updated 18/12/2023

Over the past few years, it’s become apparent that chic, fashion-forward and in-the-know homes are those brimming with house plants. From potted miniatures to glass, soil-filled spheres hanging from the ceiling and everything in between, it’s not uncommon for indoors to feel a little like the outdoors. But as our homes become more oxygenated than ever, are they becoming more dangerous for dogs? Potentially, yes, with many of the plants us humans love containing toxic compounds for our furry friends. That’s why here, we’re helping you balance the chic with the safe as we answer - are philodendrons toxic to dogs? Read up below as you begin your journey in ensuring your home is as Fido-safe as possible.

Are philodendrons poisonous to dogs?

Yes, philodendrons are poisonous to dogs, so it’s worth keeping your plant way out of your pup’s reach, or passing it onto a pooch-less neighbor. All parts of the plant contain insoluble calcium oxalate crystals which are bad news if ingested. The crystals are sharp, so are seriously uncomfortable to chew - something which is likely to deter your furry friend from taking a second bite. When fully ingested, gastrointestinal issues can follow, causing intense pain, swelling and irritation in the paths the plant crosses. Below we’ll dive a little deeper into philodendron poisoning in dogs, where we explore the symptoms your pooch might experience along with possible diagnosis and treatment.

Philodendron poisoning in dogs

So, we’ve established that philodendron and dogs simply don’t mix, but what are the effects your pooch will experience, and how serious is philodendron poisoning in dogs? Well if you think your pup’s curiosity has got the better of them and they’ve taken a bite (or ten) from your philodendron plant, call your veterinarian as a matter of urgency for advice, and potentially an appointment. For your peace of mind, we’ll explore the symptoms, diagnosis and possible treatments below.

Symptoms

Some of the symptoms of philodendron poisoning in dogs include:

• Difficulty swallowing
• Hoarse barking
• Difficulty breathing
• Excessive drooling
• Loss of appetite
• Numbness of contact area
• Pawing at face and mouth
• Swelling of the tongue and lips
• Irregular heartbeat
• Diarrhea
• Vomiting
• Dilated pupils

It is important to note that not all dogs will show obvious symptoms after philodendron ingestion.

Diagnosis

If your veterinarian advises you to visit, ideally try and find out how much of the plant your pooch ingested and take a sample with you. During your appointment, you might expect your veterinarian to perform blood tests, urinalysis, and analysis of any vomited debris. Your vet will be able to recommend the best course of action after examining your pet.

Treatments

Your veterinarian may advise that you can flush out your pup’s mouth with cold water at home, giving them some cold water to drink afterwards to ease any discomfort. Should your veterinarian advise a visit, here are some of the treatments you might expect:

• Intravenous fluids to avoid dehydration
• Antihistamine
• Gastroprotective medication
• Observation until any swelling has reduced

As always, if you have any concerns that your pet may have eaten something they shouldn’t, contact your veterinarian immediately for advice.
